Coversion from Carb to Tuned port injection - worth it?
I have a Holley carb on my mildly build Small Block 355. I don't like it because it is too big for my application, and the fuel bowls drain when I am on angles offroad.
I had planned to switch to a quadrajet carb, but I have come across a full TPI setup for $500 (yes it's checked good, 350 injections, and comes with everything I need including gaskets).
Is it worth it? I will get better fuel economy, more response and driveability, no stalling on steep hills, and if I'm lucky, a few more HP.
I ask because I just don't see spending $150 on a quadrajet, just to do the FI in a year or so. I would like to hear your opinions.

Yes to driveability, but I bet you spend double that by the time it is installed and running. Especially if you don't have a wiring harness and computer yet. One place to look at is www.jimsperformance.com for good info.

I've got an entire tpi setup laying around that came off an '86 Camaro with a 305. The car was running, though not real good. The car is getting a brand new LS engine and I don't need it. I'd sell you the whole works for less then half that including the computer. I don't have the wiring harness...Yesterday is history, tomorrow is a mystery, Live for Today!

Yes but,
My '86 TPI Z28 had to have the injectors floated every 4 months. It would start a sputterin' and missin' and crud ..... I don't really know why either, just FYI ...........

TPI works really well,I have it on my 355.
Make sure the fuel pump and tank are right.TEAMWORK is essential, it allows you to blame someone else!
I won't agree or disagree on your opinion of comp cams, but when I put a new cam in the 350 in my 76 Vette I went with Howard's and have not been disappointed. With the junk coming out of China these...
